TECHNICAL FIELD

The invention is directed to power management systems and, moreparticularly, to systems and methods for power management and prioritycharging assignments based on monitoring of electronic calendars.

BACKGROUND

Mobile computing devices such as laptop computers, portable digitalassistants (PDAs), etc. are commonly used in business to increase workerproductivity, increase communications capabilities and generallyincrease overall worker efficiency. These same types of devices are alsoused by many people for personal use such as to download informationfrom the Internet. Importantly, these mobile computing devices arepowered on batteries, which are recharged by A/C adapter power supplies.

It is not uncommon to use the internal power source, e.g., battery, ofthe device, whether it is for business or personal use. However,batteries in mobile computing devices have limited capacity (time) andhave to be recharged periodically or they will power down unexpectedlywhich, in turn, can lead to loss of information. To recharge thebattery, it is necessary for the user to plug the device into an A/Cpower source. These devices, though, begin to consume electricity withother devices on the electrical grid, such as computers, servers,appliances, etc. This places a drain on the grid, and may not useelectricity in the most efficient manner. For example, the mobiledevices may be plugged into the electric outlet during peak usage times,resulting in the batteries being charged at the highest possible costs(when they could have been charged at another time).

DETAILED DESCRIPTION

The invention is directed to power management systems and, moreparticularly, to systems and methods for power management and prioritycharging assignments based on monitoring of electronic calendars.Advantageously, the embodiments of the present invention provide acentralized control to level or balance power usage across anenterprise. The intelligent power delivery can be based on, for example,activities and/or events provided in the users' electronic calendar. Theembodiments of the present invention also increase user productivity byeliminating uncharged mobile devices and concern for finding a powersource, as well as increase ease of use for mobile device users byeliminating external power adapters. Additionally, embodiments of thepresent invention can save considerable energy costs by supplying powerto devices when power rates are the lowest, and provide the ability todetermine current and future power requirements via a communicationchannel for devices in a shared charging environment influenced by userneeds and priority factors, in addition to balancing the available powerwith business demands, and rules to achieve the most favorable outcomefor the business.

In embodiments, a power allocation controller (PAC) controls chargingcharacteristics of devices based on, for example, events and/or actionsprovided in an electronic calendar of the user's devices. The powerallocation controller can also manage power based on rules and/orpriorities and/or user requests. In embodiments, the systems and methodsof the present invention can provide weighting factors for certainactivities/events and/or priorities and/or rules and/or user requests.The power allocation controller can provide power management across anentire enterprise or within a certain location such as, for example,within a building, on a floor of the building, within a certain locationwithin a building, etc. Several methods dictating the communication,identification and authorization of charging rights of the network arecontemplated by the present invention.

By way of illustrative example, devices can have their power allocationremotely controlled by the power allocation controller based onscheduled activities/events obtained from their electronic calendar. Forexample, charging of batteries of certain mobile devices can bemonitored and controlled by the power allocation controller, based onpresent and upcoming events scheduled in an electronic calendar, inorder to ensure that, for example, a battery of one or more devices isproperly charged prior to a long trip in which electrical power may notbe available (e.g., train or airplane). In further embodiments, thepower allocation controller can control power delivery based on type orusers of the device (e.g., priority devices), time of day usage (e.g.,charge batteries prior to a meeting based on a calendar event), incombination with the scheduled activities/events.

FIG. 1 shows an illustrative system that can implement the processes ofthe invention. For example, a power allocation controller 10 includes apower allocation control module 30 for managing the processes inaccordance with the invention. To this extent, the power allocationcontrol module 30 (and/or power allocation controller 10) is operable toidentify, discover, and balance power consumption to devices 102 a-102 nin a network 106, e.g., process described herein. The network of devices102 a-102 n, can include, for example, any type of computing device suchas laptops and other mobile devices that are capable of communicatingover a network with the power allocation controller 10. The computingdevices can also be other devices in which power consumption can bemanaged by the power allocation controller, e.g., printers, gamingconsoles, etc.

The power allocation control module 30 (and/or power allocationcontroller 10) is connected to the devices 102 a-102 n by communicationschannel 100 as discussed in more detail below. In embodiments, the powerallocation control module 30 (and/or power allocation controller 10)receives activities/events from each of the devices 102 a-102 n, storedin an electronic calendar “CLDR” of each of the devices 102 a-102 n.These activities/events can be polled periodically by the powerallocation control module 30 (and/or power allocation controller 10) orpushed directly from the devices 102 a-102 n.

In embodiments, the power allocation control module 30 (and/or powerallocation controller 10) receives activities/events from one or more ofthe devices, stored in an electronic calendar “CLDR” of each of thedevices 102 a-102 n, and centrally manages power consumption of anotherdevice of a plurality of devices in the network based on the scheduledupcoming calendar events and/or activities. In this way, the receivingof a calendar event can be from one computing device, and the managingof power consumption can be provided on another (second) device, whichis different than the first device.

In embodiments, the power allocation control module 30 (and/or powerallocation controller 10) is connected to a database 22B, which may beinternal or external. The database 22B may include a look up table todetermine charging priorities and/or rules for each of the devices 102a-102 n, based on the events/activities scheduled in the respectivecalendars (which can be provided through the power allocation controlmodule 30 or devices themselves). The database 22B may also includepower grid information (peak usage times, cost of electricity forcurrent and future times of the day, etc.), and other deviceinformation. The device information can include, for example, BIOSinformation, the type of device, battery charging requirements, registryinformation, hardware configuration, software configuration, sleep moderequirements, current or historic usage of the device, locationinformation and other information that may be needed in order to balanceor manage the power consumption of the devices 102 a-102 n. This andother information can be polled periodically by the power allocationcontroller 10.

Rules can be provided to the power allocation control module 30 (and/orpower allocation controller 10) and, based on events/activities in thedevices' electronic calendar, actions can be appropriately taken by thepower allocation control module 30 (and/or power allocation controller10). By way of non-limiting examples, some rules may include, but arenot limited to, in any combination:

-   -   If conference call taken on smart phone over cell voice network,        charge the smart phone prior to a laptop that does not need        charging.    -   If conference is being held on conference room speakerphone,        then do not charge device (and allow other priority devices to        be charged).    -   If conference is on Voice Over IP using a laptop, then charge        the laptop prior to call.    -   If meeting is a customer meeting, then charge the laptop or        other appropriate device prior to meeting.    -   If meeting is revenue generating, then charge the laptop or        other appropriate device prior to meeting.    -   Is user is driving during a certain time slot that a conference        call is scheduled, then charge the laptop or other device prior        to the drive.    -   If user will not be using the laptop, but may be on conference        call on smart phone, then charge the smart phone and not laptop        prior to meeting.    -   If user is a passenger in an automobile, then charge the laptop        or other appropriate device so that the passenger can use the        device during travel.    -   If a meeting has Do Not Disturb option enabled (no email, no        phone calls) (used in face to face meetings), then the laptop or        other appropriate device may be powered down to improve charging        time.

In further embodiments, the power allocation control module 30 (and/orpower allocation controller 10) can collect information from the deviceson the network and proactively take action. These actions, for example,can be stored in the database 22B. By way of non-limiting examples,alone or in any combination:

-   -   Monitor (and/or read) all user calendars and proactively take        power management actions, depending on the upcoming events. For        example, the power allocation controller 10 can read devices'        calendars and know the power requirements for future meetings.    -   Update devices' calendars if there are power appliances        available at certain locations in which the device will be        located, and discovered by the power allocation controller 10.        For example, the power allocation control module 30 (and/or        power allocation controller 10) can update the devices'        calendars with power availability in airports, airplanes or        other transportation terminals and modes of transportation by        communicating with airport facilities and airline web sites. In        this way, the user and/or the power allocation control module 30        (and/or power allocation controller 10) can determine whether it        is necessary to charge a battery of a device, for example, prior        to any travel.    -   Determine how many participants are attending a meeting and        their power requirements. If the power requirements exceed the        capacity, the system may reschedule the meeting to a facility        that meets the requirements or provide a charge to the device        prior to the meeting. This can be done by having power        requirement information of other meeting places in the database.    -   If any devices are connected to other devices and/or require        power for computational intensive computing needs (e.g.,        connected to a projector or performing high computational work        that requires power), then the battery should be charged. The        power allocation control module 30 (and/or power allocation        controller 10) can receive such information from the computing        device, itself, through the logic of the computing device.

In still further embodiments, the power allocation control module 30(and/or power allocation controller 10) can collect requests from thedevices (or other sources such as, for example, a service provider,management, etc.) on the network and proactively take action. Therequests can, for example, be stored in the database 22B. These requestsmay be, for example, user real time on demand requests to adjust powermanagement. These requests may be provided on a priority basis such as,for example, An employee having critical job responsibilities for acompany can be provided with a charge to his/her device prior to anotheremployee having less critical responsibilities. Similarly, an employeethat is about to enter a revenue generating meeting may be provided withpriority over another employee that merely wants his/her devices to befully charged. By way of non-limiting examples, alone or in anycombination:

-   -   User can request a priority charge to charge battery 100% based        on upcoming travel.    -   User can request a best effort charge, e.g., the power        allocation controller may only allocate “x” amount of power to        the device \based on system load and energy cost.    -   User can acknowledge that there are no other power sources and        hence, requires a battery charge prior to leaving current        location.    -   User can define the time they must disconnect from power        appliance and hence require a battery charge prior to such time.    -   User can specify if computing device is required to perform        meeting function (e.g., computing device is required to project        screens for meeting) and hence require a battery charge and/or        power during a presentation.

In still further embodiments, the power allocation control module 30(and/or power allocation controller 10) can use other factors toinfluence power supply to a device. The factors can, for example, bestored in the database 22B. By way of non-limiting examples, alone or inany combination:

-   -   Present physical location of the device across an enterprise        (e.g., in a certain site location, certain building number,        certain conference room or laboratory). In these cases, the        power allocation control module 30 (and/or power allocation        controller 10) can turn off certain components of the device        depending on the location of the device, i.e., the power        allocation controller may automatically turn off GPS radio on a        smart phone to improve charging time.    -   Obtain information from corporate directory to obtain corporate        or functional hierarchy of the owner of the device in order to        make a determination as to charging priorities, (e.g., Security        or Emergency services, critical projects based on dead lines,        etc.) etc.

The database 22B may also receive information from the power grid 104,which includes peak power usages, energy costs for certain times of theday and other power management information. More specifically, the powerallocation control module 30 (and/or power allocation controller 10) maybe tied to a power company charging system 110 that influences deliveredpower at the most cost effective times. The power allocation controlmodule 30 (and/or power allocation controller 10) may also be tied intoa data center energy management system (also denoted by referencenumeral 110) that sends out a reduction signal to all conference roomsand employee offices to divert power to the most critical systems in theevent of a power failure or reduction in available power. All or acombination of this information can be used by the power allocationcontrol module 30 (and/or power allocation controller 10) to make powerconsumption decisions for each of the devices 102 a-102 n.

In embodiments, the connected devices 102 a-102 n can transmit theirrequests and/or scheduled activities and/or events directly to the powerallocation control module 30 (and/or power allocation controller 10) bythe communication channel 100 (wireless, LAN, through the AC connection,etc.). Alternatively or in combination with other embodiments, theconnected devices 102 a-102 n can provide this information to anotherdevice (e.g., control device), which would act as an intermediary withthe power allocation control module 30 (and/or power allocationcontroller 10). In further embodiments, the power allocation controlmodule 30 can poll the devices 102 a-102 n for current and futureactivities, priorities and/or rules.

In still other embodiments, the power allocation control module 30(and/or power allocation controller 10) can determine the amount ofpower it can supply to the connected devices 102 a-102 n based on totalpower consumption in the network 106, total allocated energy costs for atime of day, priority of the devices that need power, and/or time of dayusage or other parameters as discussed herein. For example, the powerallocation control module 30 (and/or power allocation controller 10) cancharge a battery of a device 102 n based on a current low batteryindication, while placing another device in sleep mode, and allowinganother device to have a low battery, since it has been detected asbeing plugged in but not in use, all based on a total allowed energyconsumption usage for the network 106. In this way, the power allocationcontrol module 30 (and/or power allocation controller 10) can controland/or manage which devices receive power, and for what period of timein order to manage the power consumption of the entire network 106.

The power allocation controller 10 can be implemented on a computingdevice 14 which includes a processor 20, memory 22A, an I/O interface24, and a bus 26. The memory 22A can include local memory employedduring actual execution of program code, bulk storage, and cachememories which provide temporary storage of at least some program codein order to reduce the number of times code must be retrieved from bulkstorage during execution. In addition, the computing device includesrandom access memory (RAM), a read-only memory (ROM), and an operatingsystem (O/S). The computing device 14 is in communication with theexternal I/O device/resource 28 and the storage system (database) 22B.

In general, the processor 20 executes computer program code, which canbe stored in the memory 22A and/or storage system 22B. The powerallocation control module 30 can be implemented as one or more programcode stored in memory 22A as separate or combined modules. Additionally,the power allocation control module 30 may be implemented as separatededicated processor to provide the function of this tool. Whileexecuting the computer program code, the processor 20 can read and/orwrite data to/from memory 22A, storage system 22B, and/or I/O interface24. The program code executes the processes of the invention. The bus 26provides a communications link between each of the components in thecomputing device 14.

The computing device 14 can comprise any general purpose computingarticle of manufacture capable of executing computer program codeinstalled thereon (e.g., a personal computer, server, etc.). However, itis understood that the computing device 14 is only representative ofvarious possible equivalent-computing devices that may perform theprocesses described herein. To this extent, in embodiments, thefunctionality provided by the computing device 14 can be implemented bya computing article of manufacture that includes any combination ofgeneral and/or specific purpose hardware and/or computer program code.In each embodiment, the program code and hardware can be created usingstandard programming and engineering techniques, respectively.

Similarly, the computing infrastructure 12 is only illustrative ofvarious types of computer infrastructures for implementing theinvention. For example, in embodiments, the server 12 comprises two ormore computing devices (e.g., a server cluster) that communicate overany type of communications link, such as a network, a shared memory, orthe like, to perform the process described herein. Further, whileperforming the processes described herein, one or more computing deviceson the server 12 can communicate with one or more other computingdevices external to the server 12 using any type of communications link.The communications link can comprise any combination of wired and/orwireless links; any combination of one or more types of networks (e.g.,the Internet, a wide area network, a local area network, a virtualprivate network, etc.); and/or utilize any combination of transmissiontechniques and protocols.

FIG. 2 shows an exemplary network 106 in accordance with aspects of theinvention. More specifically, the network 106 includes devices 102 a-102n and the power allocation controller 10. In embodiments, the network106 is a collection of devices 102 a, 102 b, 102 n in a physicallocation such as, for example, an enterprise, a building, floor, campus,etc. The network 106 includes the power allocation controller 10, whichcommunicates with the devices 102 a, 102 b, 102 n by way of e.g., LANcommunications software, Ethernet or other communications link 100 asdescribed above. In embodiments, the devices 102 a, 102 b, 102 n can beconnected to a single charging brick or station operating in a clientfashion in the network 106.

In embodiments, the power allocation controller 10 maintains the network106, which may be grouped devices (as previously described). The network106 will communicate with the devices 102 a, 102 b, 102 n via a chargingstation or individually. In embodiments, the network 106 knows eachdevice on the network 106, which can be provided by a polling mechanism,or the devices actively providing their location and other informationto the power allocation controller 10 through the network 106. In thisway, the power allocation controller 10 will know, for example, whichdevices are on the network 106, charging power budget for each device orgroup of devices, and other information such as scheduled events and/oractivities, charging priority, current and/or historic usage, type ofdevice and hardware and/or software configuration, etc.

With some combination of this information, the power allocationcontroller 10 can, for example amongst other features, alone or in anycombination:

-   -   Provide power to a device based on events and/or activities        scheduled in its electronic calendar. In embodiments, the power        allocation controller 10 can obtain information from any of the        user's device, and manage the power of any of the user's        devices. So, the power allocation controller 10 can obtain        information from a calendar of one device and provide actions        (power management) to other devices.    -   Power balancing delivered power to not exceed client charging        station requirements.    -   Power limiting of devices within the network to not exceed        mobile device charging characteristics.    -   Priority charging scheduling based on type of device (e.g.,        heart monitor vs. gaming console), user of device (e.g., doctor        vs. casual user of device), dedicated services of the device        (medical vs. gaming), etc.    -   Power balancing based on “Environmentally Friendly Policy” set        for power usage of a certain site, building, room, group of        devices, etc.

In further embodiments, the devices 102 a, 102 b, 102 c can report theirphysical location and a unique ID to the power allocation controller 10.The physical location of the devices can be provided by RF signaling,GPS methodologies or known triangulation methods, for example. Thephysical location can be used to determine the location and hence usedfor management of the devices on separate or same networks. The ID maybe an Ethernet MAC address or unique ID reported by the devices, e.g.,smart battery, or a combination of these and other identificationfactors as described herein. In further embodiments, an AC charger(e.g., brick) or client charger can incorporate a unique ID code whichis also transmitted to the power allocation controller 10 by variouscommunication mechanisms as described herein.

FIG. 3 shows an exemplary network 106 in accordance with aspects of theinvention. In this embodiment, the power allocation controller 10 isconnected in the network 106 to a smart outlet 110. The smart outlet 110and the non-smart outlet 114 (e.g., an outlet that does not includecontrol logic) can be connected to one or more devices 102 n. The smartoutlet 110 and the non-smart outlet 114 provide power to the devices 102n, which may be managed by the power allocation controller 10. Inembodiments, the smart outlet 110 can be a smart charger, for example.

In embodiments, the smart outlet 110 can provide device information tothe power allocation controller 10 through a wire or wirelesscommunication link. More specifically, in embodiments, the devices cancommunicate with the smart outlet 110, and/or directly with the powerallocation controller 10 via a communication link which may be, forexample, a LAN or even an AC signaling modulation over an AC/DC powerline. In turn, the power allocation controller 10 can provideinstructions for power management to the smart outlet 110 for managingand/or balancing power consumption by each of the devices based on theabove noted criteria or any combination thereof.

More specifically, in embodiments, the smart outlet 110 includes logicthat is configured to distribute and/or manage power to devices. Thesmart outlet 110, in embodiments, can optionally act as a network switchand provide network connectivity between the devices 102 n and the powerallocation controller 10. For example, the logic of the smart outlet 110can be programmed with the amount of power and/or other requirements forpower management for each device 102 n connected to the smart outlet 110based on, for example, priority and calendar events and/or activities.As noted above, this is possible by receiving calendarevents/activities, location and/or ID information from the devices 102n.

Accordingly, in an illustrative example, the smart outlet 110 can act asan intermediary between the devices 102 n and the power allocationcontroller 10. For example, the devices 102 n can communicate theirscheduled events and/or activities, power requirements, priorities, IDinformation, set up configurations and other information to the smartoutlet 110 (in addition to or alternatively to the information describedherein). In turn, the smart outlet 110 can provide this information tothe power allocation controller 10. The power allocation controller 10can then manage the power consumption of the devices based on theinformation provided.

FIG. 4 shows a flow for managing power consumption based on the devicesconnected to the power allocation controller, in accordance with aspectsof the invention. It should be understood that the management of thepower consumption may also be performed by the smart outlet, with orwithout instructions from the power allocation controller. In the lattercase, the logic of the smart outlet can be the same as the powerallocation controller, but implemented on a local level (local network).Accordingly, although FIG. 4 is discussed with reference to the powerallocation controller, one of skill in the art should understand thatthe processes described herein are equally applicable to the othercomponents herein.

More specifically, at step 400, the power allocation controller queriesthe devices for calendar information. In embodiments, the devices can bepolled periodically for the calendar information, in addition to otherrules and/or priorities. In other implementations, the devices canproactively provide (e.g., push) the calendar information, rules and/orpriorities to the power allocation controller.

At step 410, the power allocation controller receives information fromthe devices. This information can be, for example, any of the aboverules, priorities and/or calendar events/activities. The information canalso include, for example, battery type and/or charge, deviceconfiguration, etc., connection to other devices, computational needs,etc. as described herein In embodiments, the devices can also providelocation information via GPS, RF and/or triangulation methods.

At step 420, the power allocation controller, once the information isreceived, uses the calendar events/activities to determine which devicesrequire battery charging and/or other power needs, based on the currentand future calendar events/activities. In embodiments, the calendarevents/activities can be received from one device of the user, andmanagement of power can be implemented on another device of the user.For example, a portable device such as a smart phone may providecalendar events/activities (which may be synchronized with otherdevices) for each of the user's devices.

Additionally, at step 430, the power allocation controller can look upthe power consumption requirements of the device in a look up table,based on the calendar events/activities, prioritization and rules. Atstep 440, the power allocation may place a weight for the rules and/orpriorities and/or calendar events/activities based on preconfiguredweighting factors. For example, a device that is going to be used for arevenue generating meeting may be provided with a higher weight factorfor battery charging, than a device that is being used for email thathas available power supply and is not being used for any presentation.On the other hand, a device that is being used for a presentation in ameeting may be provided with a higher weighting for power consumption(e.g., will not have any of its components turned off) than a smartphone that is not currently in use. Weighting factors may also beprovided based on current time of day, power allocation for the entireenterprise and other situations. For example, in the case in which thetime of day is peak energy use (e.g., highest cost), then only essentialdevices may be charged. By way of illustration and non-limiting example,essential devices may be weighted higher than other devices to ensurethat they are always charged and/or receive power. These essentialdevices may be medical devices, emergency response devices, securitydevices, laptops that are required for revenue generating meetings,smart phones of top salespersons, etc.

In this way, the embodiments of the present invention can be rulesdriven and customizable by each implementation. This allows the serviceprovider, management, etc. to define a weight factor to allow the systemto intelligently calculate how power is delivered, and allow the systemto allocate/reallocate power resources as the environment changes, e.g.,new users, power grid supply, power pricing, etc.

At step 450, the power allocation controller adjusts power consumptionbased on the received information. In embodiments, the power consumptionmay also be adjusted based on total allotted power consumption for aparticular network and/or total allotted costs allowed for powerconsumption for a particular (or plural) power delivery networks.

Based on this information, the power allocation controller can managethe power consumption of each of the devices, at step 450. For example,depending on the time of day and cost of the electricity, scheduledcalendar events/activities, rules and/or priorities (whether weighted ornot) the power allocation controller may perform, as illustrativeexamples, the followingoperations/functions/instructions/determinations:

-   -   Charge batteries when peak usage and hence costs are at their        lowest;    -   Place a device in sleep mode when the device is not being used        and when there is peak usage on the grid and hence costs are at        their highest;    -   Do not charge any batteries, unless they are on a priority,        e.g., medical devices, security devices, etc. at peak usage        times, or an upcoming scheduled event has a priority and        requires a charged device;    -   Minimize power consumption of devices when there is peak usage        on the grid and hence costs are at their highest;    -   Run only those devices that are absolutely necessary, e.g.,        medical devices, security devices, based on their priorities and        upcoming scheduled event, when there is peak usage on the grid        and hence costs are at their highest;    -   Charge batteries when there is not going to be any available        power supply and an upcoming scheduled event requires device        use; and/or    -   Ensure that a total power consumption of the devices in the        network do not exceed a predetermined voltage requirement.

At step 460, the power allocation controller provides an indication tothe user of the decision (and other information such as, for example,priority) to charge the device or provide some other power managementinformation.

Accordingly, the power allocation controller provides power for multiplecomputing devices, by receiving information about these devices andcurrent and upcoming scheduled activities over a data network toreference all present and future actions, and/or other priority factorsto determine the priority in receiving levels of power delivery.Priority factors are assimilated and scalable across the enterprise ordown to an individual room or small group of power delivery ports. Inthis way, the power allocation controller determines the current andnear-term future power needs for each connected device.
